Powder and particulate substance developed by screening, cleaning, hydrolyzing treatment under high temperature and high pressure, drying and smashing of feather from carcass of fowls. Main ingredient is protein, and pupa bombycis protein for special. It is nondigestible under natural state. However its use ratio of protein will be promoted, its palatability is better after special hydrolyzing treatment. Meanwhile it will reduce cost of feeds.

Quality standard: feed grade/fertilizer grade
Physical properties: dry powder or particulate; light yellow, light brown, dark brown or black; special smell of feather powder; crude protein≥75; crude ash content≤6; crude fat≤5;
To use: in fertilizer and feed industry

Crude protein purity is about 80%-85%. Sulfur-containing amino acid content is at top level among all natural feeds. And the assay of valine, leucine, isoleucine is at top position. Feather powder has excellent effect on feather picking disease. And it is beneficial to feed at molting stage in spring and autumn.

By adding of antibiotics and additives improving animal immunity, it has fine effect on control and prevent of diarrhea disease of fur-bearing animal.
